as shown in fig. 6, when the floating plate 9 is located at the lower end inside the lubricating oil tank 5, the left bottom end face of the L-shaped pressing block 703 will be in close contact with the key on the key switch 503, so that the key on the key switch 503 is pressed, and the small-sized audible and visual alarm 502 can be turned on at this time.

The specific use mode and function of the embodiment are as follows: in the present invention, in use, the lubricating oil is first fed into the lubricating oil tank 5 through the transparent oil feeding tube 501, so that the floating plate member 9 is moved upward to the upper end inside the lubricating oil tank 5 by the buoyancy of the lubricating oil, then the wind power blade rotating shaft 3 is driven by the wind power generation blade to rotate, then the driving belt wheel on the wind power blade rotating shaft 3 drives the driven belt wheel on the pump shaft of the oil pump body 601 to rotate through the belt, so that the oil delivery pump body 601 starts to deliver the lubricating oil in the lubricating oil tank 5 to the oil inlet pipe orifice 103 through the oil delivery pipe 602 and the oil inlet shell member 603, then the lubricating oil enters the interior of the bearing main body 2 through the oil inlet 201, then the internal structure of the bearing main body 2 is lubricated, then the lubricating oil flows to the lower end of the interior of the bearing main body 2 under the action of gravity, then flows into the oil outlet pipe orifice 104 through the oil outlet hole 202, then flows back to the interior of the lubricating oil tank 5 through the oil outlet shell piece 604 and the oil return pipe 605;

when lubricating oil in the lubricating oil tank 5 is gradually consumed, firstly, the level of the lubricating oil in the lubricating oil tank 5 is lowered, then the floating plate 9 moves downwards under the action of gravity of the balancing weight 901, then the driving rack 903 is driven to move downwards, then the driving rack 903 drives the rear end gear of the transmission shaft 705 to rotate anticlockwise, so that the transmission shaft 705 drives the transmission rack 704 to move downwards through the front end gear, then the transmission rack 704 drives the L-shaped pressing block 703 to move downwards, of course, the lower end of the left side of the L-shaped pressing block 703 presses the key on the key switch 503 downwards, so that the rechargeable battery 504 starts to supply power to the small audible and visual alarm 502, and the small audible and visual alarm 502 starts to alarm.

Finally, it should be noted that, when describing the positions of the components and the matching relationship therebetween, the present invention is usually illustrated by one/a pair of components, however, it should be understood by those skilled in the art that such positions, matching relationship, etc. are also applicable to other/other pairs of components.

The above description is intended to be illustrative of the present invention and not to limit the scope of the invention, which is defined by the claims appended hereto.
